Abstract

The present invention comprises a cooking oil filter comprising a synthetic non-woven felt material and a method of filtering cooking oil utilizing a non-woven synthetic material applied at operational cooking oil temperatures.

Claims

exact text as granted — not AI-modified
1 . A filter for filtering particulate matter from hot cooking oil, said hot cooking oil having a temperature in a range of up to 204° C. (400° F.), said filter comprising: 
 at least one filter panel;    at least one filter support;    said at least one filter panel supported on said at least one filter support; and    said at least one filter panel comprising a synthetic felt filter media.    
   
   
       2 . The filter of  claim 1 , said at least one filter panel comprising a polyester felt filter media.  
   
   
       3 . The filter of  claim 1 , said at least one filter panel comprising a nylon felt filter media.  
   
   
       4 . The filter of  claim 1 , wherein: 
 said at least one filter panel having a determined operational filtering area and operational peripheral margin;    said at least one filter panel initially constructed with an initial filtering area and initial peripheral margin; and    said initial filtering area and initial peripheral margin larger than said operational filtering area and operational peripheral margin.    
   
   
       5 . The filter of  claim 4 , wherein: 
 said initial filtering area and initial peripheral margin in a range of 2% to 10% larger than said operational filtering area and operational peripheral margin.    
   
   
       6 . The filter of  claim 5 , wherein said at least one filter panel comprising a polyester felt filter media.  
   
   
       7 . The filter of  claim 5 , wherein said at least one filter panel comprising a nylon felt filter media.  
   
   
       8 . The filter of  claim 6 , wherein said nylon felt filter media has at least one glazed surface.  
   
   
       9 . The filter of  claim 6 , wherein said nylon felt filter media has at least one singed surface.  
   
   
       10 . A filter envelope for use with a cooking oil filter for filtering particulate matter from hot cooking oil, said hot cooking oil having a temperature in a range of up to 204° C. (400° F.), said filter envelope comprising: 
 a first filter panel having a first panel perimeter;    a second filter panel having a second panel perimeter;    said first filter panel and said second filter panel attachable along said first panel perimeter and said second panel perimeter to enclose a filter support; and    said first filter panel and said second filter panel comprising a synthetic felt filter media.    
   
   
       11 . The filter of  claim 10 , wherein: 
 said at least one filter panel having a determined operational filtering area and operational peripheral margin;    said at least one filter panel initially constructed with an initial filtering area and initial peripheral margin; and    said initial filtering area and initial peripheral margin larger than said operational filtering area and operational peripheral margin.    
   
   
       12 . The filter of  claim 11 , wherein: 
 said initial filtering area and initial peripheral margin in a range of 2% to 10% larger than said operational filtering area and operational peripheral margin.    
   
   
       13 . The filter of  claim 12 , said at least one filter panel comprising a polyester felt filter media.  
   
   
       14 . The filter of  claim 13 , said at least one filter panel comprising a nylon felt filter media.  
   
   
       15 . The filter of  claim 12 , wherein said nylon felt filter media has at least one glazed surface.  
   
   
       16 . The filter of  claim 12 , wherein said nylon felt filter media has at least one singed surface.  
   
   
       17 . A method for filtering particulate matter from hot cooking oil, said hot cooking oil having a temperature in a range of up to 204° C. (400° F.), said method comprising: 
 providing a filter for immersion in said cooking oil, said filter including a synthetic felt filter media and a media support; and    a filter step comprising filtering said cooking oil through said filter.    
   
   
       18 . The method of  claim 17 , wherein said method further comprises: 
 a cooking oil return step comprising returning said cooking oil to a frying apparatus.    
   
   
       19 . The method of  claim 18 , wherein said method further comprises: 
 a second filter step after said cooking oil return step comprising filtering a second quantity of hot cooking oil.    
   
   
       20 . The method of  claim 19 , wherein said method further comprises: 
 a filter scraping step intermediate said cooking oil return step and said second filter step comprising scraping accumulated particulate matter from outer surfaces of said polyester felt filter media.    
   
   
       21 . The method of  claim 20 , wherein said method further comprises: 
 at least one repetition of said filter scraping step and said second filter step.    
   
   
       22 . The method of  claim 21 , wherein said method further comprises: 
 a plurality of repetitions of said filter scraping step and said second filter step.    
   
   
       23 . The method of  claim 17 , wherein said synthetic felt filter media comprising a polyester felt filter media.  
   
   
       24 . The method of  claim 17 , wherein said synthetic felt filter media comprising a nylon felt filter media.  
   
   
       25 . The method of  claim 22 , wherein said synthetic felt filter media comprising a polyester felt filter media.  
   
   
       26 . The method of  claim 22 , wherein said synthetic felt filter media comprising a nylon felt filter media.  
   
   
       27 . The filter of  claim 24 , wherein said nylon felt filter media has at least one glazed surface.  
   
   
       28 . The filter of  claim 24 , wherein said nylon felt filter media has at least one singed surface.  
   
   
       29 . The filter of  claim 25 , wherein said nylon felt filter media has at least one glazed surface.  
   
   
       30 . The filter of  claim 25 , wherein said nylon felt filter media has at least one singed surface.
